up to the ZCON team hosting the convention to go and get their own sponsors not the ZCCA. The ZCCA only has direct contact with Nissan when it comes to sponsors.
It is time to sit with Mad Mike and Chris Karl and let them know why AMS should not be there. It may take people like Damon, Greg, Bernie and other ZCON sponsors to make them understand. Yes it will be difficult because AMS has been involved in many of the recent ZCON's but maybe it's time for that to change.
That or I guess save a spot for Vuk's Lambo at yet another Z show.
